How to Set Up a Print-Ready File: Bleed, CMYK & Resolution Explained

A print-ready file is a PDF at final size with 3mm bleed, CMYK colour, 300dpi images and embedded fonts. Getting these four things right is the difference between same-day printing and a day lost to file fixes — every product guide on this site assumes this checklist.

What is bleed and why do I need 3mm?

Bleed is artwork extended 3mm beyond the trim edge. Paper shifts fractionally during cutting; without bleed, any colour or image meant to reach the edge leaves hairline white slivers. The companion rule: keep text and logos at least 3–5mm inside the trim (the "safe zone") so nothing important gets clipped.

Why CMYK instead of RGB?

Screens make colour with light (RGB); presses make it with ink (CMYK). RGB files are converted at the press, and vivid blues, oranges and greens shift dullest in conversion. Design in CMYK — or at minimum, soft-proof in CMYK before approving — and the printed result matches your expectation. Brand-critical colours should be specified as CMYK values, not sampled from a screenshot.

What resolution do print files need?

300dpi at final printed size. A photo that fills a screen can still be far too small for print. Large-format work (A1/A0 posters, roller banners) tolerates 150dpi because viewing distance increases. Vector artwork (logos, text) scales infinitely — always prefer vector logos.

Pre-flight checklist

• PDF format (PDF/X-1a or press-quality export)
• Final trim size correct, 3mm bleed on all edges
• Crop marks on
• Text/logos 3–5mm inside trim
• CMYK colour mode; brand colours as CMYK values
• Images 300dpi at final size (150dpi for large format)
• Fonts embedded or converted to outlines
• Booklets: single pages in reading order, count in multiples of 4 (booklet guide)
• Rich black for large black areas (e.g. C60 M40 Y40 K100), plain 100K for body text

Common mistakes that delay print jobs

1. No bleed — the #1 delay; the file goes back for rework
2. RGB images — colour shift surprises at proof stage
3. Word/Canva files at screen size — export to PDF at print dimensions instead
4. Missing fonts — text reflows on another machine; outline or embed
5. Borders close to trim — thin frames make tiny cutting variance obvious; avoid or make them chunky

Export settings by software

• Canva: Share → Download → PDF Print, tick "crop marks and bleed", CMYK (Pro)
• Adobe InDesign/Illustrator: Export → Adobe PDF (Press Quality), marks & bleeds → 3mm, use document bleed
• Affinity: Export → PDF (press-ready), include bleed
• Word/PowerPoint: set page size to final size + 6mm each dimension, export PDF, flag it when ordering so trim is set manually

FAQs

What does print-ready mean? A file needing no intervention: correct size, 3mm bleed, CMYK, 300dpi, fonts embedded, exported as PDF.

Can you fix my file if it's not print-ready? Yes — minor fixes (adding bleed, converting colour) are usually quick; rebuilding artwork takes longer and may cost design time. Same-day jobs need files right first time.

Do you accept Word or Canva files? Yes, but PDF export is strongly preferred. Native files can reflow fonts and layouts on other machines.

What is rich black? A black built from all four inks for large solid areas, printing deeper than 100% K alone. Body text stays 100K to avoid registration blur.
